After the death of Amanai his mentalities changed and well, it led him to lose himself.

He defected from Jujutsu Tech.

He wanted to create a world of sorcerers and exterminate the non-sorcerers or as he called them, monkeys. Absolutely every one of them, and that included his own parents.

And there he was, in the middle of the living room, which was full of blood while the bodies lay thrown and hidden inside the bathroom, leaving traces of blood.

He breathed heavily as his gaze remained low, his cursed energy filling the house. He didn't know whether to feel remorse, he didn't really.

It was for a greater good.
